CAR-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 276,801, dated May 1, 1883.

Application tiled March 80, 1882. (N o model.)

.To all whom yit may concern Be it known that l, ROBERT P. GARSED, a citizen of the United States, residing at Nor: ristown, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Signals for Locomotive-Engines, which improvement is fully set forth in the following specilication and accompanying drawings, in which- Figure 1 isa vertical section of the signal embodying my invention. Fig. 2 is a vertical section of a modification thereof.

Similar letters of reference indicate corresponding parts in the two figures.

My invention consists in providing a locomotive-engine with a signalwhich indicates when it is in motion and at rest. For this purpose VI employ the throttle-valve, which is` within the dome of the engine, and connect therewith a pipe and signaling mechanism, whereby when the valve is operated to run or stop the engine steam is simultaneously admitted to said pipe and the signaling mechanism thereby operated, thus indicating whether the engine is running or at rest.

Referring to the drawings, A represents the steam-dome of a locomotive-engine; and B represents a throttle-valve, which is sustained within said dome, and consists of a casing, a, and valve b, the inner face of the casing constituting the seat of the valve or piston, one end of the casing-in the present case the upper endcommunicating with the dome.

In the wall of the casin g a are two ports, c c', the port c communicating with a pipe, C, and the port c with a pipe, D, the latter leading to the cylinder of the engine and the former to abarrel, E, which is properly supported in an upright position on the steam-dome, the valve b serving to cover and uncover said ports c c.

In the barrelE is a piston, F, to which is connected a stem, G, whose upper end has at tached to it the base of a rising and falling box, H, which contains a lamp, J.

K represents a signal-lantern, which is se cured to standards or supports d, connected to the barrel E, and within the lantern is fitted the lamp-box H.

It will be seenthatthe stem G of the piston F passes freely through the top `of the barrel E and bottom of the lantern K, and the pipe C communicates with said barrel below the pistou F. The sides of the lantern K are formed of dii'erent-colored glass for night-signaling* in the present case green, as at c, and red, as

Vat c'-and the box His half the height of the lantern, the sides of the box being open and the top and bottom thereof being closed, exceptin g at the centerof the top, Where there is an opening for the chimney or heat of the lamp.

The operation is as follows: When the engineis to be started the valve B is opened,

this being accomplished in the present case by drawing down the valve 7o by means of the valve-rod b. This uncovers the ports c c', whereby steam passes from the dome through thepipe D to the cylinder of the engine, and

is no longer under pressure, whereby the piston, and consequently the lamp, lowers, the light from the lamp illuminating the red glass ofthe lantern, thus indicating that the engine is standing or at rest.

Itwill be noticed that, owing to the nature of the lamp-box H, both colored glasses are not illuminated at the same time, as the bottom or top of said box acts as a shade, according to the position of the box, and thus confusion in the signals is prevented.

In Fig. 2'the valve b has a port,f, which communicates with the port c of the casiu g a. in said figure when the engine is at rest, so that steam enters the pipe C and. raises the lamp. When the engine is to be started the valve b is lowered, thus uncovering the porto and closing the port c. Steam passes to the cylinder of the engine, as usual, and also is cut 0E from the pipe G, whereby the lamp is permitted to lower. In this case the red glass is above and the green is below; butin either case the arrangement of the colors or nature of the colors may be varied, according'to the code of signals determined upon.

IOO

VIS

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent,'is-

1. The steam dome of a locomotive-engine, having within it a throttle-valve provided with an additional pipe which leads to signal-operating mechanism, said parts being combined substantially as described,whereby when said valve is operated to run or stop the engine the signal is simultaneously set, thus indicating that the engine is running or stopped.V

2. The steam-dome of a locomotive-engine, having within it a valve to which are attached two pipes, one leading to the cylinder of the engine and the other-to a barrel, the piston whereof is connected with a signaling device,

whereby when the valve is operated to run or stop the engine steam is simultaneously admitted to the aforesaid barrel or cutoff therefrom, and the lamp ofthe signaling device is moved or set to indicate that the train is running or at rest, substantially as described.

3. The throttle-valve, with the pipe D and an additional pipe, C, communicating therewith, in combination with the barrel E, piston F, stem G, lamp-support H, and signal-lantern K, substantially as and for the purpose set forth.
